INTERNAL-COBEBUSTION ENGINE Specification of Letters Patent.

Patented Dec. 17, 1907.

Application filed March 25.1907. Serial No. 364.556.

To all whom it may concern:

Be it known that 1, Euro IIOLLOCOOMBE Curr, a SllbjGCt of the King of Great Britain and Ireland, residing at51 Sinclair road,

. recess 3: formed in a bracket fixed in the cylinder West Kensington, in the county of London, England, have invented a new and useful improvement in Internal-Combustion Engines, of which the following is a specification.

This invention relates to internal combustion engines, and it consists in mounting the inlet and exhaust v'alves concentrically, the former being within the latter so that the hollow stem of the exhaust valve forms part of the induction pipe and being hot acts as a vaporizer for the incoming charge and in providing means for regulating the temperature of said vaporizer.

In the accompanying drawing :Figure 1, Sheet No. l, is a view in side elevationpartly in section of one method of carrying the present invention into efiect, Fig. 2 Sheet No. 2 is avicw in plan showing the inlet and outletto" the jacket of the valve box and an alternative construction of the clamping ring, and 3, Sheet No. 3, is a broken view in sectional elevation showing an alternative construction.

Throughout the views similar parts are marked withlike letters of reference.

The inlet valve a and the exhaust valve b are arranged concentrically with respect to one another, the inlet valve being within the exhaust valve the stem 6 of which has a passage a" through it. a This stem is mounted in a detachable annular box 0 adapted to be head as in any convenient manner, preferably by forming a seating :0 within the cylinder head with which a seating c on the box c engages. The box is held in position by means of a clamping ring y which may either y on one side and a forked or slotted part f on the opposite side as shown in Fig. 1 or with a fork at each end as shown in Fig. 2. The tongue 3 is adapted to engage a slot or carried by the cylinder head so and the slotted part y is engaged by a nut g on a stud y fixed This box is formed chamber 0 which forms an.

in the cylinder head. with an annular independent water jacket round the valves.

This chamber has a suitable inlet a and outlet 10 provided with means, such a stop cock, whereby the flow of water through the said chamber can be regulated so as'.to vary be formed with a tongue the temperature in the vaporizer. In the cylinder head 00 and valve box 0 are openings :11 v

and '0 through which a lamp or other means of initially heating the va orizer can, be introduced for starting when ieavy oils are em ployed. Similar openings x and c are provided for the escape of the exhaust gases. In the hollow stem 6 of the exhaust valve b are mounted perforated guides a a -for the stem a of the inlet valve a. The external diameter of the stem a of the inlet valve and the internal diameter of the hollow stem b of the exhaust valve are such that there is an annular passage or chamber a. between the stem of the inlet valve and the inner wall of the hollow stem of the exhaust valve which forms a vaporizer which is in communication with the fuel supply by means of the pipe a which is a sliding fit in the hollow stem b of the exhaust valve. In the part of this annular passage or chamber between the guides a and a are placed a series of metal balls (I or their equivalents which operate to thoroughly break up and atomize the incoming charge as being loosely packed in the chamber they are moved or agitated each time the valves open and close.

In some cases provision may be made for further agitating or imparting movement to the balls by forming ridges or recesses r on or in the stems of one or both of the valves.

The inlet valve may .be operated either atmosphcrically, or mechanically, by means of a screw 12 carried by a rocking lever 'v as shown. The inlet valve a is controlled by the spring a located within the upper. end of the assage or chamber a through the stem of the exhaust valve and taking a bearing on the upper side of the guide a The exhaust valve 6 is controlled by the spring 6 and is operated by a rocking lever o, the forked end of which contacts a flange b on the stem 1) of the valve.

It will be seen that with a multiple cyli11- (ler engine embodying theherein dcsc'ibed improven'icnt access may be readily obtained to the interior of any one of the cylinders", or any one of the valve boxes may be removed while the engine is running, which construc tion is particularly useful for marine purposes. I
